Problems solved by technology
[0010] If the input voltage range of the RF power amplifier is relatively large, the number of voltage values to be calibrated m+1 is relatively large during calibration. After the number of m+1 is large, the calibrated transmission power will be more, which will lead to calibration The time is relatively long, because the calibration time directly affects the production efficiency during the production process, so the above-mentioned existing technology will lead to an increase in production costs and a decline in product competitiveness

The invention discloses a calibration method of a radio frequency (RF) power amplifier and a device. The method comprises the following steps: selecting a plurality of voltage values within the numeric area of the input voltage of the RF power amplifier; determining the transmitted power which needs to be calibrated under various voltage values, wherein, the transmitted power which needs to be calibrated under part of the voltage values are part of the transmitted power between the minimum transmitted power and the maximum transmitted power under the voltage values; and calibrating the transmitted power which needs to be calibrated under various voltage values. Compared with the prior art in which the calibration range under each voltage value is the whole range from the minimum transmitted power to the maximum transmitted power, the calibration method of the invention reduces the transmitted power which needs to be calibrated, thereby reducing calibration workload, shortening calibration time, and being beneficial to improving production efficiency of products, reducing production cost of the products and enhancing product competitiveness.
Description
technical field [0001] The invention relates to the technical field of communications, in particular to a calibration method and device for a radio frequency power amplifier. Background technique [0002] At present, the size of electronic products is getting smaller and smaller, and the heat problem is more serious. The power consumption of RF power amplifiers (Power Amplifier, PA) occupies a high proportion in electronic products. At present, many products start to reduce the voltage of RF power amplifiers or The power consumption of the radio frequency power amplifier is reduced by dynamically adjusting the voltage of the radio frequency power amplifier in the use. Since lowering the voltage of the RF power amplifier or dynamically adjusting the voltage of the RF power amplifier during use may cause the RF index to exceed the standard, it is necessary to make some modifications in debugging and calibration. [0003] The prior art provides a method for calibrating a radio...
